Definitions
- the purification of titanium tetrachloride which entails the removal of different impurities contained in particular in the ore itself is a process which is carried out in steps. One of these steps consists in removing the vanadium which is present. It is also known that the treatment of titanium tetrachloride with different organic compounds and more specifically with mineral or vegetable oils makes it possible to extract the vanadium by means of a process of cracking the organic substance and reducing the vanadium to the state of nonvolatile compounds. The distillation of the titanium tetrachloride which has been treated in this manner results in a product which is free of vanadium.
- the process referred to has a disadvantage in that a small quantity of organic substances is permitted to remain in the titanium tetrachloride and must consequently be removed. In point of fact, these impurities make the tetrachloride unfit for the fabrication of titanium metal and also interfere with the proper course of operations when the tetrachloride is oxidized with a view to obtaining titanium oxide pigment.
- the proportions of aluminum chloride vary between the limits of 0.05 and 3% and preferably between 0.1 and 1% by weight with respect to the weight of titanium tetrachloride.
- the aluminum chloride is added to the boiling titanium tetrachloride and the mixture is refluxed for a certain period of time.
- a constant-level titanium tetrachloride distillation column having a capacity of 3 tons is supplied at a rate of 750 kgs. per hour with vanadium-free titanium tetrachloride containing ppm. of carbon in the form of soluble organic compounds (with the exception of carbonyl chloride).
- the distillation column receives simultaneously 0.1%, namely 750 grams of anhydrous aluminum chloride which is introduced at a rate of 375 grams at half-hourly intervals. It is apparent that, on completion of the initial filling operation, a proportion of 0.1% of anhydrous aluminum chloride corresponding to a quantity of 3000 grams will have been fed into the distillation column.
- a process of purifying titanium tetracholride contaminated by carbonaceous impurities but substantially free of vanadium which comprises distilling the contaminatecl titanium tetrachloride in the presence of about between 0.05 to 3% by weight with respect to the weight of titanium tetrachloride, an additive consisting essentially of anhydrous aluminum chloride.
- a process of purifying titanium tetrachloride contaminated by carbonaceous impurities but substantially free of vanadium which comprises adding to boiling contaminated titanium tetrachloride about 0.05 to 3% by weight with respect to the weight of titanium tetrachloride, and additive consisting essentially of anhydrous aluminum chloride, and removing titanium tetrachloride from the mixture thus obtained by distillation.
